Earlier, the IEC undertook to investigate the voting station in Wellington after a video posted on Facebook showed black and white voters queuing separately, with the person shooting the video denouncing it as racist.

The video was viewed more than 125,000 times and shared more than 470 times within three hours of being posted by Chumani Siimane.

Lawson Naidoo, executive secretary of the Council for the Advancement of the South African Constitution, said the organisation had advised IEC officials at several voting stations in the Western Cape to have a separate queue for people filling in VEC4 forms.
